Description

Mostly we think of dahlias as being packed with hundreds of pointy petals, but often in the garden simplicity is better—and this is where Dahlia 'Mexican Star' comes in. It is in the single-flowered Dahlia category, meaning that it has just one layer of petals. But what petals! Blooming from mid-summer until the first frosts of autumn, the flowers—which are 6cm across—have petals of a mesmerizing, rounded, dark chocolate-red, and a bright yellow disc in the centre.

The blooms of Dahlia 'Mexican Star' are full of depth and drama—and they have a lovely, almost chocolate-like fragrance. Plants will grow to 90-120cm in height, and they are supported by dark stems and lightly bronzed, dark green foliage.

Dahlia 'Mexican Star' is likely to flower a little later than many other Dahlia varieties, so it usefully extends the colour season in your garden. Deadhead regularly to encourage more flowers. The blooms look stunning in a sunny mixed border or patio pot. Incidentally, they are perfect for cutting, and bringing indoors, too.

Dahlia 'Mexican Star' is a unique crossing/hybrid between Cosmos atrosanguineus and a Dahlia. It is also known as Dahlia × Cosmos 'Mexican Black'.

Useful information

    • Dahlia 'Mexican Star' is half hardy, which means that it should be kept frost free over winter and during spring.

    • For best results, start your dahlia tubers in temporary pots in a
      greenhouse in March or April to grow on to transplant outside later in the season—this will give them a head start.

    • Alternatively, you can plant the Dahlia 'Mexican Star' tubers directly outside in May.

    • Plant with the stump of last year's stem facing upwards. The tuber should be fully submerged but with the stump just below the soil surface.

    • Plant one tuber per 8-10" pot if growing on during spring. When
      planting outside, space the tubers around 30-50cm apart from each other. Compact varieties don’t need so much space.

    • Water-in thoroughly after planting and continue to water regularly once in full growth, but only when the soil appears to be nearly dry.

Dahlias in 60 seconds

Dahlias like full sun and a free-draining soil, and should be lifted and stored in winter, or at least protected with peat or straw. Dahlia flowers can range from 5 to 25cm in diameter and those magnificent larger-flowering dahlias might appreciate a little extra support with canes!
